Overview#
The MTU 8V1600 DS350 is a 350 kW diesel standby generator set powered by the MTU 8V1600G70S — a 14.0-liter, 8-cylinder V-configuration turbocharged and charge-air-cooled diesel engine producing up to 408 kWm (547 bhp) gross at 1,800 rpm. The engine uses common rail fuel injection and is governed by MTU's ADEC (Advanced Diesel Engine Control) electronic isochronous governor, delivering ±0.25% speed regulation under steady-state load.
The DS350 carries EPA Tier 3 certification and is available in all standard North American voltages from 208V to 600V three-phase — all voltage configurations offered with UL 2200 listing and CSA certification as options. The prime rating is 325 kW, making this unit appropriate for installations where occasional prime power duty is anticipated.
Standard equipment includes a unit-mounted radiator rated for 50°C ambient, 24V electric start (1,050 CCA), brushless 4-pole PMG alternator (PMG standard on 570-frame), and the MTU digital control panel with CANBus ECU communications, NFPA 110 compatibility, and IP 54 front panel protection. IBC seismic certification and OSHPD pre-approval are available as options.

Our Service Experience#
The MTU 8V1600G70S is the entry point into the MTU 1600-series diesel platform — a purpose-built power generation engine with common rail injection and ADEC electronic control. Unlike the R-series units which use John Deere automotive-derived engines, the 1600-series is MTU proprietary and requires MTU-trained technicians for any ECU-level diagnostics or fuel system service.
At 350 kW and 14.0 liters, this engine has moderate specific output and typically shows good reliability when operated on clean fuel with consistent service intervals. The ADEC controller is sophisticated but sensitive to connector corrosion — in coastal or high-humidity environments, plan for annual connector inspection and dielectric grease application.
Fuel consumption at 350 kW is significant: 26.5 gph at full load means a 500-gallon base tank provides approximately 18 hours of runtime at full load. Size the tank for your longest anticipated outage duration plus 25% reserve.
Frequently Asked Questions#
What engine does the MTU 8V1600 DS350 use? The MTU 8V1600G70S — a 14.0-liter, 8-cylinder V-configuration diesel engine with common rail fuel injection and ADEC electronic isochronous control. This is an MTU proprietary engine, distinct from the John Deere engines used in the smaller R-series generator sets.
What EPA tier is the DS350? EPA Tier 3 certified. The 1600-series was introduced before the Tier 4 Final mandate for this power range (>750 kW boundary), and the DS350 carries Tier 3 certification per the spec sheet.
What voltages are available on the DS350? 208V, 240V, 480V, and 600V three-phase (380V and 440V are also listed). UL 2200 listing and CSA certification are available as options on the 208V, 240V, 480V, and 600V configurations.
What is the fuel consumption at 75% load? 21.7 gallons per hour on diesel #2. At 50% load, consumption drops to 16.3 gph. Plan fuel storage and delivery based on your expected average load factor for standby applications.
